Application August 19, 1933, Serial No. 685,798 "12 Claims. (G1, -158) This invention relates to means for mounting cards, pictures, clippings and other items insheet ,form,, and one ebject of the invention is to in- ,clude as apart of such mounting means a transparent covering to protect the card or, picture while leaving it wholly visible, and, in fact, en- The invention consists in certain features and elements of construction in combination as herein shown and described, and as indicated by the claims.

, In the drawing: .f

Figure 1 is a plan or face view of a blank of transparentmaterial constituting one element of ,the structure.

Figure 2 is a rear face view of an insert sheet to be combined with the blank of Figure 1..

Figure 3 illustrates said parts combined in the position of use, with the marginal flaps of the transparent material folded over the insert.

Figure 4 is a face view of the structure shown in Figure 3, and including a card or picture mounted therein.

Figure 5 isa view similar to Figure 3 showing a modified form of the device. f 1,

Figure 6 illustrates a triangular insert.

Figure '7 shows a further modification produced by dividing the structure of Figure 5 diagonally,

Figure 8 is a front face view of the structure shown in Figure land illustrating the device in use.

Heretofore, it has been proposed to mount photographs, post cards and other pictures by means of small pocket-like devices adhesively secured to a mounting sheet in position to engage the .corners of the card or picture, and in some instances such devices have been made of transparent material, such as celluloid or cellophane, so as to leave the entire area of the card or picture clearly visible. The present invention provides a which completely means for seboard or the leaf of an album. Figures 1 to 4 form of the invention, and Figure 1 shows asheet of transparent material, such as celluloid or cellophane, designed to serve as the cover sheet, 1, cludes a rectangular area with marginal flaps, 2

of the assembled device. It inbe folded over along'the dotted to embrace an insert and 3, adapted to lines of Figure 1 so as sheet, 4, like that shown in Figure 2. The rear surface of i dicated. by the stippling in Figure 2, so that the I thesheet, 4, may be gummed, as infaces for attachment to gummed area which is not covered by the flaps,

2 and 3, when the'parts are assembled, as shown in Figure 3, may be moistenedfor adhesively securing the assembled structure to a mount.

Such mounting of the assembled device will not be effected untilafter the picture, clipping or other sheet matter has'been mounted upon the opposite or outer face of the insert, 4, for display through the transparent wall of the cover sheet,

1, as seen in Figure. 4. l

Of course, if the picture, .card or the like is trimmed to exactly fit the rectangle formed by the lines of fold at which the flaps, 2 and 3, are turnedpver, there will be no necessity for actually securing it to the outer face of the insert, 4, but if it should be slightly smaller than the insert, as for example, the picture, 7, shown in Figure 4, it may be definitely positioned thereon by adhesive securement to the tabs, 8, partially cut from the central area of folded outwardly to present their gummed surthe rear face of the pictabs" is indicated in Figthe triangular spaces, 8*, are

ture, 7. This use of the ure 3,in which,

' formed by the outward folding of .the tabs, 8.

The insert sheet, 4, is also provided with additional tabs, 5, adapted to register with slots, 6, out in the flaps, 2 and 3, of the transparent member, 1, so that when the sheet, 4, has been properly positioned under said flaps, 2 and 3, it may be interlocked with them by protrusion of the tabs, 5; through the slots, 6; and this arrangement .provides for more complete adhesive securement of the assembled parts to a mount since the gummed surfaces of the tabs, 5, will thusbe presented back of the transparent flaps, and can be attached directly to the mounting surface, This tends to hold the mounting-device more closely against the surface than if it were secured only by the adhesion of the central portion of the insert,-4. l

Figure 5 illustrates a device which is in all respects similar to that of Figure 3, except that it is. square in outline; this permits of an additional use. Instead of employing the device for completely enclosing a picture to be mounted, it may be cut diagonally into two triangular corner holders so thatwith four such trianagular holders a rectangular picture of considerable size may be secured to a mount in the manner indicated in Figures '7 and 8. The square 'device includes a transparent member, 11, with marginal flaps, l2, folded over at all four sides. The square insert sheet, l3, is gummed on its rear surface, as indicated by the stippling in the drawing, and is,

the insert, 4, and

i said insert being gummed on formed with tabs, 15, which interlock with slots, 16, in the flaps, 12. If the device is used for completely enclosing a picture, or for example, for mounting a postage stamp in an album, the stamp or picture may be secured to the insert, 13, by means of the turned-over tabs, 18, leaving apertures, 18 which appear in Figure 5.

When employed in a corner holder of triangular form, the insert sheet, of course, becomes triangular, as'seen at 14 in Figure 6, and may be interlocked with the flaps, 12, by means of its tabs, 15. The corner of the picture, 20, which is to be mounted, is then slipped between the insert and the transparent outer face of the part, 11 The exposed gummed rear surface of the insert, 14, is then moistened, and, if desired, the flaps, 15, may also be moistened for adhesively securing the triangular corner holder to the face of the mount (not shown). If desired, the flap, 18, may be folded back over the front face of the insert sheet, 14, and moistened for adhesive securement to the back of the picture, 20, to fasten the latter permanently in the pocket.
